⚡ Power Math & Safety Analysis
The Jackery Explorer 300 delivers 300W of continuous power, which comfortably exceeds the Portable Shower Pump’s 40W operating draw. This gives you a 260W safety margin.
After accounting for 85% inverter efficiency, the usable capacity is 249Wh. Dividing this by the appliance’s power draw yields approximately 6.2 hours of continuous runtime.
Pro Tip
For cycling appliances, real-world runtime is longer. With a 15% duty cycle, expect 41.5 hours of elapsed time before depletion.
